“…It is expected that this channel has the highest BER among the whole channels due to the influence of SRS. The variation of the BER of the highest-frequency channel is investigated for the seven UWB-WBM systems and the results are depicted in Figure (12) The results in Figures ( 12 and 13) are presented for the highest-frequency channel, which is expected to have the highest BER among the channels, and for 𝑁𝑠 = 1, 2, and 3 spans. Investigating the results in these figures reveals that there is an optimal lunch power (𝑃 𝑐ℎ ) 𝑜𝑝𝑡 which minimizes the BER.…”

“…In addition, both bands may share the same photonic devices such as optical amplifiers [6]. Further, scientific and engineering research has propagated toward S+C+L system where the three bands have the lowest attenuation window in standard single-mode fiber (SMF), which is considered as a very achievable way for expanding transmission capacity [7], [8], [9], [10], [11], and [12]. Covering S to U band has been also investigated to obtain both higher capacity and spectral efficiency as done in [13] due to its lower band attenuation values.…”

This paper discusses the development of a seven-band coherent wavelength-division multiplexing (WDM) system covering the T to U systems, aiming to enhance the capacity and system efficiency. Seven multiband systems (C+L, S+C+L, S+C+L+U, E+S+C+L, E+S+C+L+U, O+E+S+C+L+U, and T+O+E+S+C+L+U) are designed with 40 GBaud symbol rate, 50 GHz channel spacing, and dual-polarization (DP)-16QAM signaling. The analysis adopted the enhanced Gaussian noise model, considering the amplified spontaneous emission of inline optical amplifiers and nonlinear interference (NLI) from fiber nonlinear optics, including Kerr effect and stimulated Raman scattering (SRS) which it implemented using Matlab (Ver. 2020b) program. The results show that the optimal powers are -4, -5, -5, -4.5, -3.5, -6, and -4.5 dBm for the seven WDM systems, respectively. Further, with a fiber span length of 100 km, the C+L system has the longest transmission reach of 20 span. However, using S+C+L+U system gives the highest bit rate-distance product of 1619 Tbps.km. The O+E+S+C+L+U and T+O+E+S+C+L+U systems are designed with 50 km-span length to reduce the effect of NLI caused by the large numbers of channels (1060 and 1200, respectively).

“…For example, a design of an octagonal PCF with six air hole rings is proposed in Reference [11] that obtains a negative dispersion of −239.5 ps/nm.km at 1550 nm. Selim habib et al proposed a design based on holey fibers in [12] which exhibits negative dispersion coefficient of −470 to 850 ps/nm.km over S to L-bands. Furthermore, a design of a spiral microstructure fiber is proposed in Reference [13] that obtains −327 ps/nm.km at 1550 nm.…”

A Modified Design of a Hexagonal Circular Photonic Crystal Fiber with Large Negative Dispersion Properties and Ultrahigh Birefringence for Optical Broadband Communication

In this paper, we propose a modified design of a hexagonal circular photonic crystal fiber (HC-PCF) which obtains a large negative dispersion and ultrahigh birefringence simultaneously. The optical properties of the proposed HC-PCF were investigated using the finite element method (FEM) incorporated with a circular perfectly matched layer at the boundary. The simulation results showed large negative dispersion of −1044 ps/nm.km and ultrahigh birefringence of 4.321 × 10−2 at the operating wavelength of 1550 nm for the optimum geometrical parameters. Our proposed HC-PCF exhibited the desirable optical properties without non-circular air holes in the core and cladding region which facilitates the fabrication process. The large negative dispersion of the proposed microstructure over the wide spectral range, i.e., 1350 nm to 1600 nm, and high birefringence make it a suitable candidate for high-speed optical broadband communication and different sensing applications.

Ultra-High Negative Dispersion Based Single Mode Highly Nonlinear Bored Core Photonic Crystal Fiber (HNL-BCPCF): Design and Numerical Analysis

et al. 2020

View full text Add to dashboard Cite

In this paper, two different models of highly nonlinear bored core photonic crystal fibers (HNL-BCPCF) are presented and compared for attaining an ultra-high negative dispersion coefficient and high nonlinearity. We achieved this dispersion by tailoring a defect into the solid core of the two proposed models and appropriately scaling down the diameter of the neighboring airholes of the core. To investigate the optical transmission properties in the fiber, simulations were carried out employing the finite element method (FEM) having a perfectly matched layer. The simulation results exhibited large negative dispersion coefficients of − 2218 ps/(nm-km) and − 2221 ps/(nm-km) for the two proposed models, respectively, when the wavelength had been tuned to 1550 nm and the corresponding nonlinear coefficients stand out to be 117.6 W −1 km −1 and 118.4 W −1 km −1. The fabrication process had been made much more feasible as the design consists of circular airholes. In our analysis, this geometry of photonic crystal fiber is noticeably more robust for its successful achievement of an ultra-high negative dispersion with high nonlinearity and facilitates optical back propagation applications and dispersion compensation for optical transmission systems.
